I was wondering that too and had also forgotten her name. Google says Carrie Gracie. Her Wikipedia page says she was born in 1962, so she may have retired. It also says she had a degree in Chinese, which would require some intellect, I suspect.
I only discovered recently that the BBC scrapped Dateline London in October after 25 years. I thought it was a good programme, even when she presented it, though I didn't think she was as good as some of the other presenters, including Shaun Ley. She was better when reporting from China, I think. Shaun Ley is apparently being dumped from reading the news too, along with a slew of other presenters, some of whom have taken voluntary redundancy, in a merger of the news channels.
